How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)? In the context of physics, explain the statement, "The moon is falling." How does a satellite function in relation to Newton's three laws?
Calculating Free Energy & Cell Potential Step 1: Identify the given values. Note: Depending on the requirement of the problem, proceed to Step 2 or Step 3 Step 2:Calculate Gibb's free energy of the cell using the expression, ΔG=nFE∘ where, ΔG is Gibb's free energy of the...
If you see "normal" as "expected," even in the chemical sense this is more or less on target: A normalized preparation is one that has been created in proportion or relation to an established standard. To discover how to calculate the normality of NaOH, or how to convert from normality ...
The expression in parentheses,k2/KM, is known as the specificity constant,also called the kinetic efficiency. After all of this pesky algebra, you finally have an expression that assesses the catalytic efficiency, or enzyme efficiency, of a given reaction. You can calculate the constant directly ...
Heat Energy Calculator To calculate the energy required to raise the temperature of a known mass of a substance, you use the specific heat formula: **Q = m × c ×ΔT** **Qis the energy transferred in joules,m** is the mass of the substances in kg,cis the specific heat capacity ...
Step 2:Use the formula to calculate the specific heat of the substance. To find the specific heat, we must use the equation $$C_{p}=\frac{Q}{m\Delta T} $$ Plugging in the mass, the heat energy added, and the change in temperature, we get: $$C_{p}=\frac{1000}{(2)(5)}...
3. Calculate Molarity Divide the number of moles of NaCl by the volume of the solution to get molarity. 0.21 moles ÷ 0.59 liters = 0.356 M. References Royal Society of Chemistry: Periodic Table ThoughtCo: What Is a Mole in Chemistry?
If the object is a cuboid, and you know its dimensions instead of the volume, click on the Calculate volume section and enter the cuboid dimensions. Right away, the calculator will give you the density of the object. You can click on the unit to change it to any other unit. It also ...
